    Question 11-18-2011
    Hi all,
    Replaced my 91 GP engine with a salvage yard one.
    When I did that I replaced the front mount as well.

    Whenever the tranny shifts either up or down it is rock hard like I am doing it at the wrong RPM.

    Any suggestions?

    It feels hard even at slow accelerations.

    Thanks JC

    P.S. it always bangs into gear going up or down... never a smooth shift...
